CHURN.

To all 1v/wm it may concern.'

Be it known that I, JosErHUs B. SELLMAN, a citizen of the United States,residing at Texarkana, in the county of Miller and State of Arkansas,have invented certain new and useful Improvements in Churns, of whichthe following is a specification.

This invention relates to improvements in churns, and more particularlyto the operating mechanism of the same.

With these and other objects in view, the invention consists in certainnovel features of construction as hereafter shown and described, andthen speciiically pointed out in the claim, and in the drawingsillustrative o-f the preferred embodiment of the invention: Figure 1 isan elevation, partly in section, of the improved device; F ig. 2 is aview similar to Fig. 1 showing a slight modication in the constructionand likewise show- .ing the device arranged as an ice cream freezer.

Corresponding and ,like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved device comprises a supporting frame including a base 10preferably mounted upon caster wheels 11, and with four-corner posts 12rising therefrom. One pair of the corner posts is connected at the upperends by a transverse member 13, while a similar transverse member 14connects the other pair of corner posts. Extending over the transversemembers 13-14 is an upper plate or support 15. The corner posts whichsupport the transverse member 13 are connected by a tie rod 16, while asimilar tie rod 17 connects the posts which support the transversemember 14. Rising from the transverse member 15 is a center post 18, thepost being rigidly supported from the member 15 by suitable braces 19.At its upper end the center post 18 is preferably rounded or globular asshown at 20.

Supported upon the transverse member 15 at opposite sides of the post18, are standards 2122. The standard 21 is provided with a relativelylong bearing 23 which extends to and engages against one side of thepost 18, while a similar bearing 24 extends from the standard 22 towardand bears against the opposite side of the post 18. The post 18 isprovided with a transverse aperture in alinement with the bores of thebearings 23-24. A stub shaft 25 is Specification of Letters Patent.

mounted for rotation in the bearing 23 and extends at its inner end intothe aperture of the post 18, while a similar stub shaft 26 operatesthrough the bearing 24, with its inner end extending into the apertureof the post 18 and against the inner end of the shaft 23. The two shafts25-26 abut end to end within the post 18 and thus assist in supportingthe standards and their bearings. Connected to the outer end of theshaft 25, is a beveled gear 27, while a similar beveled gear 28 isconnected to the outer end of the shaft 26. The beveled gears areprovided respectively with operating handles 29-30. By this means thebeveled gears with their shafts may be independently rotated.

The standard 21 is provided with a vertical bearing 31, while a similarvertical bearing 32 is carried by the standard 22. A vertical shaft 33is supported in the bearing 31 and carries a beveled pinion 34 engagingwith the beveled gear' 27, while a similar vertical shaft 35 issupported in the bearing 32 and carries a beveled pinion 36 engagingwith the beveled gear 28.

Supported upon the base 10 is a milk or cream receptacle 37 having adetachable closure preferably formed in two parts 38 and providedrespectively with knobs 40-41 to facilitate the handling of the closuremembers. Extending through t-he closure members 38, are two dasher rods42-43 having sockets 44-45 secured to their upper ends. The socket 44 isprovided with an upwardly directed bearing sleeve 46 having a verticalslot 47, While a similar bearing sleeve 48 extends upwardly from thesocket 45, and is provided with a vertical slot 49. The vertical shaft33 extends into the bearing sleeve 46, while the shaft 35 extends intothe bearing sleeve 48. A pin 50 extends through the slot 47 and into theshaft 33, while a similar pin 51 extends through the slot 49 and intothe shaft 35. By this means the shafts 33-35 are detachably coupledrespectively with the dasher rods and communicate their motion theretoas hereafter explained. At their lower ends the dasher rods are reducedto form bearings to engage in suitable steps in the bottom of thereceptacle 37. The dasher rod 42 is provided at its lower end with apaddle 52, while a similar paddle 53 is connected to the lower end ofthe dasher rod 43. The lower portions of the dasher rods are preferablyformed square,

and adjustably connected respectively to the square portions of thedasher rods are other paddles 54-55, the latter paddles being preferablyadjustable upon the dasher rods by any suitable means, as for instanceby set screws 56-57. By this means the movable paddles may be adjustedto correspond to the depth of the milk or crea-m within the receptacle.By this means it will be obvious that an eectual churn device isproduced containing two sets of paddles which are independentlyoperative, or which may be actuated in concert as preferred, or one ofthe paddles may be actuated in one direction, while the other paddle isoperated in the opposite direction. It will also be obvious that thedasher rods may be readily uncoupled from their operating shafts toenable the cream receptacle to be removed when required.

In Fig. 2 the device is shown arranged for use invoperating an ice creamfreezer, and in this arrangement the post 18 is replaced by two posts 65rigidly supported from the plate 15 and provided with braces 66. Theposts 65 are maintained in separated position at their upper ends by atransverse member 67. Otherwise the structure above the plate 15 is notchanged, as will be obvious. The receptacle 37 is replaced by tworeceptacles 68-69 to contain the freezing mixture for an ice creamfreezer, and located within the receptacle are the cans 70-71 in whichthe cream is frozen. When the improved device is employed for an icecream freezer, the dasher rods 4t2- 43 are replaced by other rods 72.73at the lower end of which the ordinary ice cream paddles are attached,one of the paddle devices being represented conventionally at 74. Bythis arrangement two cans may be simultaneously frozen as will beobvious.

Having thus described the invention, what is claimed as new is:

In an apparatus of the class described7 a supporting frame includingbase corner posts and an upper supporting structure, vertical supportshaving horizontal sleeves with the bores thereof in longitudinalalinement, stub shafts carried by said bearing sleeves and extendinginto said supporting structure, a receptacle carried by said base,dasher rods operating in said receptacle, and means for transmitting themotion of said stub shafts to said dasher rods.

In testimony whereof I affix my signa* ture in presence of twowitnesses.
